The 80kW dual-gun modular AC-DC fast charger targets public parking hubs and retail destinations, where uptime and quick service access decide revenue. With CCS2 outlets, a 200V-1000V DC window and OCPP 1.6J connectivity, it delivers predictable high-power charging while keeping installation and commissioning simple. This DC fast charging station pairs high utilisation with low maintenance overhead.

1. Modular AC-DC Power Topology and Conversion Chain Every cabinet is load tested before shipment and arrives with a wiring map covering contactors, fuses and surge arrestors for fast commissioning. The 80kW dual-gun unit is built around a modular AC-DC topology that rectifies three-phase AC input onto a regulated DC bus before power reaches the vehicle inlet. Input power factor stays above 0.99 and the wide input window keeps operation stable on weak rural feeders and long industrial spurs. Efficiency peaks at 96 percent and stays above 94 percent from light load to full output, cutting energy cost for high-utilisation sites. Commissioning takes under an hour with the guided setup wizard. Matching power modules are documented in the datasheet.

2. 200V-1000V Wide Voltage Output With Constant Power Cable assemblies rated 250A to 400A are matched to each outlet, and CCS2 leads are available in lengths from 4 to 8 metres. Voltage and current limits are negotiated over the control pilot, then confirmed by the battery management system before the DC contactors close. A 1000V ceiling future-proofs the investment, because the same DC fast charging station serves today’s 400V fleets and tomorrow’s 800V platforms. Continuous insulation monitoring isolates the outlet whenever leakage approaches the configured threshold, protecting technicians and vehicles alike. Pre-charge sequencing limits inrush current, shielding vehicle contactors and DC link capacitors from stress during every plug-in.

3. 20kW Hot-Swap Power Modules and N+1 Redundancy Modules slide out from the front, so service engineers never need rear clearance in tight parking layouts or wall-adjacent installations. Speed-controlled fans and intelligent airflow keep acoustic noise near 65 dB, which suits residential, hospital and retail locations. Module-level diagnostics flag degrading fans and capacitors long before they cause a stoppage, enabling condition-based maintenance. Thermal design holds junction temperatures stable at 50 degrees ambient, so the DC fast charger sustains rated output in hot climates. Power is delivered by 20kW hot-swappable modules, so a failed unit is exchanged in minutes without isolating the whole cabinet. Compatible EV charging connectors are listed separately.

4. Dynamic Power Allocation Across Dual Outlets Scheduling profiles prioritise buses in the morning and light vehicles in the evening without manual intervention. Matrix switching allows any module to serve any gun, so one cabinet can run a single 125A session or two lower-current sessions. Dynamic power allocation distributes available capacity across outlets in real time, letting a single vehicle draw the full 80kW. Operators set allocation rules per site, per connector or per tariff window through the cloud portal, with no on-site reprogramming. Load balancing also watches site demand, trimming total draw when the transformer or building load approaches its limit. Session logs record delivered energy per outlet, which simplifies billing, reconciliation and fleet cost allocation. Site rules are tuned from the operator portal.

5. Outdoor IP55 Enclosure Built for Public Sites Each unit is ingress tested at the factory and ships with CE documentation covering insulation and earth continuity checks. The enclosure is rated IP55, with filtered intake louvres and a sealed electronics compartment that shrugs off rain, dust and washdown. Surge protection, residual current detection and emergency stop are integrated, and the cabinet is engineered for a ten-year outdoor service life. Ambient range runs from minus 30 to plus 55 degrees Celsius, with internal heaters protecting the 7-inch display in freezing conditions. Optional heating, ventilation and lighting kits extend operation to cold storage yards and dusty mining roads. Installation drawings cover plinth and cable routing.

6. Smart Payment, OCPP Management and Energy Integration Local storage keeps sessions running if connectivity drops, then synchronises records once the link returns. Remote diagnostics, firmware updates and tariff changes are pushed over the air, cutting truck rolls for routine maintenance. An open API and Modbus TCP option let the DC fast charger link with solar, storage and building management systems. Communication runs over OCPP 1.6J, so the station integrates with almost any back office without custom middleware. Multi-language interface, configurable tariff screens and branded start pages help operators monetise the charging session itself. Drivers authenticate by RFID card, mobile app, QR code or ISO 15118 plug and charge, with an optional POS terminal for bank card payment. Backend integration follows the OCPP specification.

Deployment Support and Accessories

Projects usually pair the cabinet with Type 2 to Type 2 cables and a OCPP protocol controllers, all supplied from one factory. Engineering teams can review the company profile before order, while commercial questions go through the contact our team page. Standard builds ship in four to six weeks, and documentation covers wiring, grounding and network setup.

Frequently Asked Questions

Does the station support solar and battery storage integration?

The DC bus is storage-ready. Solar MPPT or a BESS cabinet can feed the link directly, and the controller can cap grid import during peak tariffs. This suits microgrid and carport projects where demand charges dominate operating cost.

What payment options are available for public drivers?

RFID card, mobile app, QR code, ISO 15118 plug and charge and an optional POS terminal for contactless bank cards. All methods write to the same metered session record, so reconciliation stays simple. Connector options are listed on our EV charging connector page.

What output voltage range does the 80kW unit support?

The charger delivers 200V to 1000V DC at up to 125A, so it serves 400V passenger cars and 800V heavy vehicles from the same outlet. Constant power holds 80kW from about 500V upward, which shortens charging time on modern high-voltage packs.

How does DCDC architecture differ from a conventional AC-DC charger?

A DCDC stage accepts a DC bus from solar or battery storage and converts it directly, skipping one rectification step. That raises round-trip efficiency and lets the modular AC-DC platform operate during grid outages when paired with a BESS cabinet.

Can the two guns charge at the same time at full power?

Yes, with dynamic allocation. Total capacity is shared, so one vehicle can take the full 80kW, or two vehicles can split it according to state of charge. Matrix switching means any module can serve either outlet, and rules are configured remotely.

Which OCPP version should an operator choose?

OCPP 1.6J covers the widest installed base of back offices today. OCPP 1.6J is specified here for certificate handling, plug and charge support and stronger message security. Both profiles work with standard roaming hubs, and the protocol controller datasheet explains the mapping.
